# Whether to Use Continuity Correction When Conducting a Test of Equality of 2 Proportions

I am using the command in R to conduct a test of equality of two proportions:

prop.test(x=c(226,181), n=c(365,335), correct=F)


The p-value varies slightly if I turn on the correct=T. Can anyone tell me that whether I should use correction in this case?

• correct=TRUE is for considering Yates' continuity correction.

• Yes, I know. But should I consider continuity correction in this particular case? I am thinking that the n is large so the answer is no... Dec 7 '15 at 3:16
